JOHN H. RAMBERG, OF CHICAGO, ILLINOIS.

SASH HOLDER.

To all whom it may concern:

Be it known that I, JOHN H. BA BERG, a citizen of the United States, residing at Chicago, inthe county of Cook and State of Illinois, have invented certain new and useful Improvements in Sash Holders, of which the following is a specification.

My invention relates to sash holders and has for one of its objects the provision of a simple and efficient holding mechanismfor holding window sashes in desired positions of elevation.

A further object is the provision ofmeans for reducing friction between window sashes and their frames.-

A still further object is the provisionof accommodating windows to frames having irregular saslrengaging surfaces.

Other objects will appear hereinafter.

An embodiment of my invention is illus trated in the accompanying drawing, forming a part of this specification, and in which- Fig. 1 is a front elevation of a window construction with a portion broken away to expose underlying parts and embodying my invention;

Fig. 2 is an enlarged fragmental section showing details of the construction; and

Fig. 3 is a section taken as on line 33 in Fig. 2.

In the drawing I have indicated a window construction of more or less conventional construction. It will be understood that my invention is applicable to conventional forms of window constructions and may be embodied in new constructions or attached to window constructions already in use.

I have indicated a window frame 4 in which are mounted sashes 5 and 6. The sashes 5 and 6 may be mounted in the frame at in any desirable manner, such as that now in common practice.

In the sides of the frame 4 adjacent the edges of the window sashes 5 and 6 I cut away portions providing recesses T and in these recesses may be provided a metallic member 8, which in the present instance is indicated as being of sheet material struck up to provide suitable facings for the recesses 7. It will be apparent that the metal facing 8 may be dispensed with, but it will be found that with the use of the metal facings the construction will be much more durable. I preferably provide one of the series Specification of Letters Patent. Patented 14 1922 Application 1 filed Kay 14,

1820. Serial No. 881,255.

of recesses adjacent each edge of each of the sashes 5 and 6, and these series of recesses preferably extend from, the bottom to the top of the frame 4, although theyv may be formed in lengths to suit different requirements. It will also be apparent that the recesses 7 may be formed in different sizes and spaced at different distances apart to accommodate the requirements of desired windows.

In each of thesashes 5 and 6 I provide one or more rollers and mountings for engaging the recesses7. In the present instance I have indicated one'of these rollers andmountin'gs at each corner of the sashes 5 and 6. It will be apparent, however, that a fewer or greater numberof these rollers and mountings may be'supplied whenso desired. The rollers and mountings are similar in construction and method of applying them to the sashes, hence a description of one will suffice for all.

Each roller construction is provided with a housing 9 adapted to be set in a suitable recess 10 formed in one of the sashes 5 and 6. The casing 9 preferably fits the recess 10 more or less snugly and has foot members 11 thereon to be secured to the sash by means of wood screws 12, or the like. The casings 9 may besecured in the sashes in any desirable manner. Each case is preferably formed of sheet material formed substantially U-shaped and provided with slots 13 in two of its opposite sides with ends of the slots adjacent the edge of the sash. At said ends of the slots 13 and at the edge of the sash the casing 9 is open, as indicated at 14 in Fig. 3.

Disposed in the casing 9 is a substantially U-shaped member 15 which has its leg portions adjacent the leg portions of the casing 9. Formed in the ends of the member 15 are recesses 16 which register with the slots 13 in the casing. Disposed in the recesses 16 and slots 13 are the ends of a roller shaft 17. Between the legs 15 on the shaft 17 is a roller 18. The roller 18 is of such a size as will extend out through opening 14 .in a manner to engage a recess 7 in the frame at. To reduce friction at the ends of the roller 18 I have provided washers 19. It will be apparent, however, that these washers may be dispensed with when so desired.

To the bight portion of the member 15 I attach a pin 20 which engages a perforation in the bight portion of casing 9. The sash is preferably cut away sufliciently to permit the movement of the pin out through the casing 9, as clearly indicated in Figs; 2 and 3. Disposed around the pin 20 and between the bight portions of member 15 and casing bottom of the recesses 7 lightly if so desired, or, they may be made so that the shaft 17 will not quite touch the bottoms of said slots when the roller is engaging the lining 8 of the recesses 7 With the use of a sash holder at each corner of each sash such sash will not bind due "to uneven surfaces in the window frame. -Somet1mes the wlndow frame 1s not smooth orthereis greater space at the top than'at the bottom ofthe frame. The'resilient device of the roller-in my device will accommodate all of these irregularities.

A sash holder comprising an elongated piece of sheet material disposed in U-form; a piece of sheet material disposedin U-form with its leg portions slidably mounted between and against the leg'portions of the first-mentioned U-formed piece, there being slots in the first-mentioned U-formed piece of material and notches in the ends of the second-mentioned piece of sheet material registering with said slots; a shaft disposed in said notches and slots; a roller on said shaft and extending out between the leg portions of both of said U-shaped sheet material pieces; spacing members atand engaging the sides ofsaid rollers;a pin fixed in the bight portion of the second sheet mate- 'rial piece and slidably mounted in the bight portion'of said other piece of sheet material; and a compression spring around said pin and between the big-ht portions of said U-shaped pieces of sheet material.

In testimony whereof I have signed name to this-specification on this 12th day of May, A. D. 1920.
